This week, we have a Euproops sp. horseshoe crab from Indiana.  This specimen comes from Daviess County, Indiana.  The fossils date to the Pennsylvanian Period.  This deposit is a little younger than the Mazon Creek fossil deposit at around 305 million year old.  More information about Euproops sp. can be found in Mazon Monday #21.

This fossil is owned by ESCONI member Rich Holm.
